摘要

随着对可持续航运解决方案的需求日益增长,替代能源和环保技术已成为研究的重点领域。本研究探讨了在沿海和内河船舶燃料电池动力系统中使用氢燃料和氨燃料的技术经济可行性。开发了三个系统边界框架:一个由使用氢的质子交换膜燃料电池提供动力,另一个由使用氨的固体氧化物燃料电池提供动力,还有一个使用传统二冲程柴油发动机的比较系统。为 "瀚海五号 "集装箱母船开发了一个适用于沿海和内河航线的燃料电池动力系统模型,并考虑了不同航线上的停靠时间、货舱损耗和载荷变化等运行条件。模型试验的沿海航线设置在大连港和烟台港之间,内河航线设置在武汉港和上海港之间。对船舶寿命期内的燃油消耗、温室气体排放和经济效益进行了全面的定量分析。结果表明,新动力系统案例在沿海航线上最多可减少排放 5 160 万吨,在内陆航线上最多可减少排放 1.16 亿吨。虽然氢气和柴油动力系统在短途航线上显示出更大的经济效益,但随着航程的增加,氨气与这些燃料之间的经济差距也在缩小,这凸显了氨气在长途航线上的应用潜力。

Evaluating fuel cell power systems for coastal and inland waterway vessels: Technical and economic perspectives
With the growing demand for sustainable shipping solutions, alternative energy sources and environmental protection technologies have become key areas of research. This study investigates the techno-economic feasibility of using hydrogen and ammonia fuels in fuel cell power systems for coastal and inland waterway vessels. Three system boundary frameworks were developed: one powered by a proton exchange membrane fuel cell using hydrogen, another by a solid oxide fuel cell using ammonia, and a comparative system using a traditional two-stroke diesel engine. A model of a fuel cell power system for coastal and inland waterway routes was developed for the “Han Hai V” container mother ship, considering operational conditions such as docking times, cargo space loss, and load variations on different routes. The model testing was set between Dalian Port and Yantai Port for coastal routes, and between Wuhan Port and Shanghai Port for inland routes. A comprehensive quantitative analysis of fuel consumption, greenhouse gas emissions, and economic benefits over the vessel’s lifespan was conducted. The results indicate that the new power system cases can reduce emissions by a maximum of 51.6 million tons on coastal routes and 116 million tons on inland routes. While hydrogen and diesel-powered systems show greater economic benefits in shorter routes, the economic gap between ammonia and these fuels narrows with increasing distances, highlighting ammonia’s potential for long-haul applications.

期刊介绍: The journal Energy Conversion and Management provides a forum for publishing original contributions and comprehensive technical review articles of interdisciplinary and original research on all important energy topics. The topics considered include energy generation, utilization, conversion, storage, transmission, conservation, management and sustainability. These topics typically involve various types of energy such as mechanical, thermal, nuclear, chemical, electromagnetic, magnetic and electric. These energy types cover all known energy resources, including renewable resources (e.g., solar, bio, hydro, wind, geothermal and ocean energy), fossil fuels and nuclear resources.
